P6KE12A-B from Littelfuse, in a DO-204AC(DO-15). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Cathode | passive | Cathode axial lead of the unidirectional TVS, marked by the color band; connect to the positive/protected line, with reverse stand-off voltage VR of 10.20 V min and breakdown VBR of 11.40 V typical (10.20/12.60 range per table) for the P6KE12A. |
| 2 | Anode | passive | Anode axial lead of the unidirectional TVS (end opposite the cathode band); connect to ground/return, with forward voltage VF below 3.5 V at 50 A for single die parts. |
